Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser pulses, the new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or…

Buying drugs on the street is a game of Russian roulette. From Xanax to cocaine, drugs or counterfeit pills purchased in non-medical settings may contain life-threatening amounts of fentanyl.  Physicians like me have seen a rise in unintentional fentanyl use from people buying prescription opioids and other drugs laced, or adulterated, with fentanyl. Heroin users in my community in Massachusetts came to realize that fentanyl had entered the drug supply when overdose numbers exploded.In 2016, my colleagues and I found…

A new research report is out, revealing price information for used Galaxy S22 series models as well as the iPhone 13 and Pixel 6. Unsurprisingly, the iPhone 13 is the best at retaining resell value, in line with previous generations. Despite being the newest of the three, the Galaxy S22 is the worst at maintaining resale value. That’s either good or bad news for the Samsung handset, depending on your perspective. The market research comes from SellCell. That’s the same company that discovered iPhone 13…

Elon Musk said that Tesla may stop taking orders on some models of its popular electric vehicles because of the long delivery timelines. There’s currently a rush to order electric vehicles as the technology gains momentum – both naturally, as it becomes more mainstream, and in the short term, more directly through the gas price increase. For Tesla, we previously reported that this has resulted in a significant increase in its order rate in several regions of the US. In March, this resulted in many Tesla models…

The New York Times moved swiftly to change Monday's answer to its daily Wordle puzzle out of fear that it would be seen as some sort of commentary on the debate over abortion rights.The game, which became a sensation late last year and was bought by The Times in January, gives users six tries to guess a different five-letter word each day.Yet The Times scrambled when it discovered that Monday's word, which had been entered into Wordle's computer programme last year, was “fetus.”The timing was particularly fraught given…

The Chhatrapati Shivaji Maharaj International Airport will remain shut for all flight operations for six hours on May 10 to carry out pre-monsoon maintenance and repairs, an official has said.

Planets outside of our Solar System are rather dull things. So dull, we can only see them directly by sifting out a scattering of reflected rays amid the glare of their parent star. Even then, the best we can manage is a pinprick to identify its position.  Gathering enough light to reveal intricate details of these distant worlds would require a lens far larger than anything we can construct. One wider than Earth. Wider than Jupiter, in fact.Fortunately, cosmic-scale lenses happen to exist already. Thanks to the way that…

I wanted to love the Garmin Vivosmart 4 back when it launched in 2018. It was a chic yet capable fitness band, with a great set of fitness tracking features for the price. It was almost perfect, except for one major flaw: the touchscreen. Swipes didn’t register like they were supposed to, and the capacitive button was even more finicky. So when I first unboxed the $149.99 Garmin Vivosmart 5, I breathed a huge sigh of relief. There, at the bottom of the display, was a beautiful, physical button. Adding a button might…
